A46b 15/00 U.S. Cl.15256.5 2 Sheets Drawing. 8 Pages Specification VACUUM COLLECTORCONTMNER A rotatable cleaning element such as a brush or beater bar forremoving residual toner particles from a cleaning web is provided. Theremoved toner particles create a cloud within a housing through whichthe cleaning web moves along an endless path. A vacuum is applied to thehousing to create a moving airstream for removing the cloud of tonerparticles from the housing. This cleaning brush comprises a cylindricalroller having a raised cleaning surface thereon made of material in theform of a right-hand helix extending from a midpoint on the surface ofthe roller toward one end thereof and a lefthand helix extending from amidpoint toward the opposite end of the roller. This material can be anap or brush material of well known construction for rubbing or beatingagainst the cleaning web or a raised rib or lobe on the roller. Thecleaning brush is rotated in a direction so that the right and left-handhelical configuration causes the cloud of toner particles to be directedtoward the center of the cleaning web so that toner does not tend tocollect on side walls of the housing.
